A woman from the tribe of Khath'am asked for the verdict of Messenger of Allah ﷺ (regarding something) during Hajjat-ul-Wadaʿ while Al-Fadl bin ʿAbbas was the companion-rider behind Messenger of Allah ﷺ. She asked, "Allah's ordained obligation (i.e. compulsory Hajj) enjoined on His slaves has become due on my old father who cannot sit firmly on the riding animal. Will it be sufficient if I perform the Hajj on his behalf?" He said, "Yes." (Using translation from Bukhārī 4399)
أَنَّ امْرَأَةً مِنْ خَثْعَمَ اسْتَفْتَتْ رَسُولَ اللَّهِ ﷺ فِي حَجَّةِ الْوَدَاعِ وَالْفَضْلُ بْنُ عَبَّاسٍ رَدِيفُ رَسُولِ اللَّهِ ﷺ فَقَالَتْ يَا رَسُولَ اللَّهِ إِنَّ فَرِيضَةَ اللَّهِ عَلَى عِبَادِهِ أَدْرَكَتْ أَبِي شَيْخًا كَبِيرًا لَا يَسْتَطِيعُ أَنْ يَسْتَوِيَ عَلَى الرَّاحِلَةِ فَهَلْ يَقْضِي أَنْ أَحُجَّ عَنْهُ؟ قَالَ «نَعَمْ»
